Portal 2 (2011)

Another excellent by Valve. Enjoyed P1 and this one was still fun too. Think I got stuck on 2 puzzles while the rest usually figured it out after a break. Nice dialogue as always.

Metro 2033 (2010)

Really enjoyed Metro 2033. While it is linear, it made sense since your usually underground in a train/subway tunnel. Levels still roomy enough to move around in. A good S.T.A.L.K.E.R. light alternative when you don't want a heavier open ended world.
